I have remarked that, when I re-entered Kúkawa, the cultivation of the ground had not yet begun; indeed, the whole country was so parched, that it became even a matter of perplexity to find sufficient fodder for the horses; for the whole stock of dry herbage was consumed, and of young herbage none was to be had. It is stated in my memoranda, that on the 5th of August I paid twelve rotl for a “kéla kajímbe,” or large bundle of dry grass; an enormous price in this country, and sufficient to maintain a whole family for several days; but that was the most unfavourable moment, for in a few days fresh herbage sprang up and made good all deficiencies. While speaking on this subject, I may also mention, that the herbage of Kúkawa, being full of “ngíbbi,” or _Pennisetum distichum_, horses brought from other countries generally fare but badly on it, as they are reluctant to fill their mouths with its small prickles. Rain was very plentiful this year, 1851, and I am sure would, if measured, have far exceeded the quantity found by Mr. Vogel in 1854. Indeed, there were twelve very considerable falls of rain during the month of August alone, which together probably exceeded thirty inches. It must be borne in mind, moreover, that the fall of rain in Kúkawa does not constitute the rule for the region, but is quite exceptional, owing to the entire absence of trees and of heights in the neighbourhood. Hence, the statement of Mr. Vogel in one of his letters[1], that the line of tropical rains only begins south of Kúkawa, must be understood with some reserve; for if he had measured the rain in the woody country north of that capital, between Dáwerghú and Kalíluwá, he would, in my opinion, have obtained a very different result. It is evident that all depends upon the meaning of the expression, tropical rain. If it imply a very copious fall of rain, Kúkawa certainly does not lie within the limit of tropical rain; but if we are to understand by it the regularly returning annual fall of rain, produced by the ascending currents of heated air, it certainly does.[2] There was a very heavy fall of rain on the night of the 3rd of August, which not only swamped our courtyard, but changed my room, which lay half a foot lower, and was protected only by a low threshold, into a little lake, aggravating my feverish state very considerably, and spoiling most of my things.
